A Hard-Body assembly/apparatus with a deck and cabin (FIGS.  1 - 2 ). Which is designed to fit over a generic inflatable pontoon. The hard-top apparatus significantly increases the useable space and the applications to which inflatable boats can be adapted.

BACKGROUNG

[0001] 1. Field of Invention:

[0002] Inflatable Watercraft.

[0003] 2. Prior Art:

[0004] The conventional inflatable boat has been on the market for well over twenty years, and this is decidedly well into the public domain.

[0005] Early inflatable boats were made from animal skin that were joined together and inflated to form a floating raft type transport device. These “Skin Boats” were made by inflating the hide of small animals.

[0006] Eventually, “inflatables” were made of rubber with separate air compartments or bladders insulated from each other. This particular design feature made it possible for the craft to remain afloat even when there was a tear in one of the air-filled bladders. In part, for ecological reasons the inflatables were later constructed out of synthetic materials.

[0007] Early inflatable “rafts” were powered with sails, long poles and oars to move them manually; with the invention of the gasoline engine inflatables were equipped with motors.

[0008] Newer modifications for inflatables have included the addition of a console, a steering wheel hard floors and hard bottoms. In particular, on the larger inflatables, the consoles have been centered on the floor of the craft allowing sufficient room to walk around the circumference of the console. Some consoles have been equipped with a soft-top or “bimeny” over the console area.

[0009] (a,b) These prior art modifications to the generic inflatable did not, however, constitute anything which approached a “cabin” design and none have included a hard surface deck area around the circumference of the pontoon inflatable.

[0010] The conventional prior art inflatable craft design provides a pontoon type structure with bladders filled with air. The conventional prior art inflatable is actually more of a raft than a boat.

[0011] Prior Art Cont'd:

[0012] Prior art craft operated by sitting low in an open-air craft. They have no windshield, no substantial cover from the elements, and have a limited capacity to carry equipment, accessories and heavy loads.

[0013] (a,b) The flexible material provides no significant support for passengers to walk around on and does not provide sufficient support to place equipment on the surface of the bladders.

[0014] (-) The conventional art does not have “bumper” protections around the (vertical) circumference of the craft to protect the bladder from excessive wear and this exposure increases the potential of rips and tears of the air-filled bladder.

[0015] (-) The conventional art does not allow easy access beyond the transit area, beyond the stern of the boat where there would be more accessibility to the engine(s) or for more access for fishing purposes.

[0016] (c,d) The prior art provides fewer options for controlling the excessive bounce and lift at the front end. Which is a common occurrence with conventional inflatables; though speed, per se, is not a factor that differentiates the prior art from the new design, the hardtop increases the stability of the front end and contributes to holding down the front end at high speeds.

[0017] An associated problem is that the prior art inflatable also has a greater tendency to capture wind and lift up at the front as well as a greater tendency to capture the hit waves on the underside of the nose of the craft causing additional instability. This degree of instability also makes it less seaworthy.

[0018] The conventional art is excessively “wet” in that it provides fewer protections from the elements for passengers, equipment and food; and it is more prone to attracting moisture through condensation as well.

[0019] Prior Art Cont'd:

[0020] (e) The prior art provides fewer protections from ocean spray, hot sun and other harsh elements common to the ocean and other out door aquatic areas. The safely usable range of the conventional art inflatable is further limited for reasons such as these.

[0021] (f) The number of passenger and type of equipment the conventional inflatable is capable of carrying in safety and comfort is restricted by its basic design that has been unchanged for generations.

[0022] (g) Generic prior art is produced by forming large flexible tubes with insulated bladder type compartments capable of holding air without leaks. These are produced by production machinery out of durable composite materials.

[0023] Objectives and Advantages:

[0024] The hard-top deck and cabin assembly promulgated here reconstitutes the concept of an inflatable boat as understood by persons skilled in the art of constructing and using the type of watercraft.

[0025] When permanently attached to the pontoon inflatable “raft”, the deck and cabin assemblies constitute a quantum leap in the design and utility of inflatables as the world has known them.

[0026] The hardtop deck and cabin assembly, in effect provides the best of both worlds!

[0027] A) Conventional boat features with B) The low-to-the-water profile and rugged excitement associated with inflatables.

[0028] (a,b) The hard-top deck and cabin assembly/apparatus attaches to the inflatable bladder, providing a hard durable surface upon which passengers can safely walk around the circumference of the boat, and upon which accessories can be permanently secured. This is impractical and really impossible on the prior art inflatable without a hardtop.

[0029] Objectives and Advantages, Cont'd:

[0030] (c,d) Though, it is preferable for the weight of the cabin to be light, the weight which is provided as well as the design of the deck and cabin themselves, create additional balancing properties to the craft and contribute to the stability of the front end of the hardtop design inflatable.

[0031] Consequently the excessive lift and bounce that occurs with prior art inflatables at high speeds or in rough water is reduced by the design and weight of the hardtop. Further, this utility design inflatable is therefor substantially more seaworthy than the prior art open raft design.

[0032] The design of this inflatable craft can range from a square shape or box design to a more aerodynamic and streamlined look. Persons familiar with the prior art will immediately notice that strikingly different appearance and should welcome the hearty character and expanded uses this rugged boat can accommodate.

[0033] (-) The hardtop design inflatable has a constructed “bumper” type protective cushion around the (vertical) circumference of the boat, which also contributes to the impact protection at the nose of the boat.

[0034] (-) The nose assembly part of the new design inflatable is designed to accept strong frontal impact as well as to push or bump objects loose or assist other craft and dislodge them when immobilized.

[0035] Indeed, the nose assembly is structurally independent from the deck and cabin so that the event of a strong frontal impact, damage would be minimized to the main structure of the hardtop design inflatable.

[0036] The nose cone is not designed, nor is it intended to hold the assembly apparatus together. Therefore, it does not have a direct structural connection with the rest of the craft.

[0037] (e) The hardtop portion of this utility inflatable craft significantly reduces the amount of moisture which gets into the boat by providing cover for spray; it also significantly reduces moisture from condensation and keeps passenger, food and equipment dryer than any craft located so low to the water.

[0038] Objectives and Advantages, Cont'd:

[0039] The hardtop portion of this inflatable design also provides significantly more protection from the sun and other harsh elements common to the ocean and other aquatic areas.

[0040] (f) Due to the increased protection and stability, the hard top design significantly increases the range, comfort and safety with which this hybrid craft can be operated.

[0041] The hard-top design inflatable makes it possible to safely carry more passengers and to hook-up surprisingly more accessories compared to a conventional inflatable of the same size.

[0042] (-) These benefits prevail under adverse weather conditions.

[0043] (-) The extended deck area at the rear of the boat allows easy access beyond the transit area, beyond the stern of the boar, creating accessibility to the engines(s) from the deck area as well as creating more access beyond the transit area for fishing purposes.

[0044] (-) With the (hardtop) deck and cabin assembly attached, the useable space is increased by 60 to 75%.

[0045] (-) Approximately one-thing ({fraction (1/3)}) of the boat remains a pontoon and the balance is transformed into a useable seaworthy floating surface containing desirable features of conventional boats and inflatables as well.

[0046] (-) Spacewise, (i.e. the relative total useable space prior to the redesign) the raft or pontoon of the boat now constitutes about one-third of the craft and the (hard-top) deck and cabin assembly now constitute the balance of the craft which now has more useable space and can now carry more weight due, in part, to the capability of dispersing the weight throughout the additional structure of the boat.

[0047] (-) This craft is now more seaworthy and the additional useable space created by the hard top is substantial.

[0078] Summary:

[0079] This utility hardtop design inflatable is a hybrid watercraft, which produces unexpected results by combining the features of conventional hard body craft with those of inflatables. This utility design significantly expands the useable surface as well as extends the range (distance) that the users of inflatables will be able to safely travel. The scope of applications/uses to which inflatables can be adapted is also significantly increased.

[0080] Description—Main Embodiment: FIGS. 1 to 16

[0081] A typical embodiment of the utility hard top 20 is illustrated in FIG. 1 and FIG. 2, which slow isometric views of the apparatus. Detail of the AFT support platform 40 are not shown here, however they appear in FIG. 14.

[0082]FIG. 3 shows the shape of the baseboard 22 and FIG. 4 shows a more detailed view with the proximate locations of the support ribs 32 located under the baseboards 22.

[0083]FIG. 5 provides a front view of the assembly/apparatus with the cabin 24 wheelhouse 26 area. A side view of the utility hard-top is shown in FIG. 6 with particular attention to the wheelhouse 26 part of the cabin. FIG. 7 shows the detail for the vertical construction of the cabin 24 and FIG. 8 provides detail of the wheelhouse/cabin window 30.

[0084]FIG. 9 shows the shape of the cabin 24 and the location of the hatch 28 at the starboard portion of the craft.

[0085]FIG. 10 provides the details of the support ribs 30 which are to be located throughout the underside of the baseboards 22.

[0086]FIG. 11 shows the shape of the support rib for the nose assembly 38 which is actually a regular support rib which has been cut in half and the right side is used as the support rib located at the nose or “bumper” of the craft. This rib is, of course, smaller than a regular support rib-{fraction (1/2)} it's size. Notice that the right half of the rib 38 is a different shape than the left side 30 of the typical support rib. This allows for the slight slant/angle at the nose of the craft and a better fit for the front—most portion of the boat. These nose templates/ribs are situated in a vertical rather than a horizontal position facing in a starboard direction (FIG. 13).

[0087] Description—Main Embodiment: FIGS. 1 to 16 Cont'd:

[0088]FIG. 12 shows the detail of the nose cone assembly 38 and Fig, 13 illustrates the position(s) of the two support ribs 34 for the nose cone assembly.

[0089]FIG. 14 provides detail of the AFT support platform 40 which is necessary to provide additional support and to contribute to the integrity of the structure at the rear of the craft. a more

[0090]FIG. 15 provides a profile and a top view of the generic inflatable pontoon which is in the public domain yet is an integral part of this utility hard-top inflatable craft. FIG. 16 illustrates how the utility hard-top would fit over the inflatable. FIG. 17 may be submitted at a later date—it would be a photograph of the invention which has already been built and tested in the ocean environment.

[0091] Best Mode of Production/Construction:

[0092] The best mode of construction is to use the injection mold procedure for building the hard-top portion and to use the conventional production procedure for the bottom, inflatable portion of the craft. The production method for the inflatable pontoon is essentially the same as that used with the conventional art. Specifically, the pontoon is created with production machinery out of composite materials.

[0093] Prototype Construction/Assembly Method:

[0094] The prototype hard-top has been constructed manually, using plywood as the primary building material.

[0095] (-) The hard-top portion is constructed by cutting parts (i.e. templates, ribs, platform, cabin, AFT support, nose cone apparatus) that are assembled. To form an apparatus which will fit over a generic inflatable pontoon. This apparatus will provide a source of shelter and circumference walking support for persons using the watercraft.

[0096] The templates or ribs are designed to fit under the plywood platforms and over the air filled pontoon surface.

[0097] Prototype Construction/Assembly Method Cont'd:

[0098] The cabin is constructed of plywood and is attached to the flat plywood platforms (i.e. the deck assembly). The front of the assembly contains a hatch or lid and the rear of the assembly is finished with an AFT support platform. The plywood is covered with resin and they pointed with marine paint.

[0099] The completed/assembled hard-top is placed over and can be permanently or temporarily attached to the air filled pontoon. On the prototype (plywood) model the top portion is connected to the pontoon by generic strap-on-break away belts and turn buckles located around the platform deck. This hard-top assembly can also be manufactured by using the injection mold procedure (preferred), by shaping aluminum sheet metal, by using fiberglass mold and a variety of other methods and materials. Then be attached to the pontoon using the same method and hardware that was used in the prototype.

[0100] The best mode of construction is the injection mold procedure using strong composite materials for the top portion and use the conventional production procedure for the bottom, inflatable portion of the craft.

[0101] Operation—Main Embodiment:

[0102] The craft is operated in the same manner as a motorboat or generic inflatable or other run about watercraft. Skill in use is largely dependent on the experience of the operator in the use of watercraft.

[0103] Description and Operation—Alternative Embodiments:

[0104] A broad review of alternative embodiments, used and modes of operation are covered in the ramifications and conclusions section which follows immediately.

[0105] A key alternative embodiment includes the ability to interchange parts of this utility hard-top to reflect the particular use to which it will be put.

[0106] Description and Operation—Alternative Emdodiments Cont'd:

[0107] For example, should the craft be used for a “sport” recreational event, the square shaped top can be removed and a streamlined, aerodynamic top portion can be installed in a matter of a few minutes.

[0108] This procedure and application can follow a “legos” type construction method whereby prefabricated, inter-changeable parts can be easily installed and the entire appearance of the craft as well as its primary utilitarian purpose can be quickly modified.

[0109] The alternative embodiments are intended to capture the imagination of the person who purchases a craft such as this because the nature and style of this utility hardtop can be modified by purchasing and installing the variety of accessories which will be made available to the owner of a “stewcraft”tm inflatable boat.

[0110] In effect, the owner of a “stewcraft”tm will be able to design his/her own boat.

[0111] The interchangeable parts will be constructed of durable materials using the injection mold procedure recommended as the best mode of production. The particulars of the design and manufacture of these interchangeable parts fall primarily in the realm of those who are expert in the injection mold field and we would leave it to these people to advise us on these matters.

[0112] An alternative embodiment pertaining to the operation of this craft can include the use of this utility inflatable for “extreme sports” on the water.

[0113] The invoice can operate this craft with the same degree of skill that it takes to operte a conventional inflatable; and the experienced seaman can use the stewcraft tm to test the limits of his skill in the open ocean provided he first equips this craft with the accessories necessary to venture for out into the sea.

[0114] Indeed, the craft can be modified to be exceptionally seaworthy—however, as with any vehicle, after a certain point the skill and judgement of the operator becomes a critical factor when one goes beyond the threshold of conventional use.

[0115] Description and Operation—Alternative Embodiments Cont'd:

[0116] This professional race car driver does not perform in a conventionally equipped vehicle yet, he must have exceptional skill in operating the vehicle. Similarly, this new design inflatable can open the door to a new water sport for skilled professionals.

[0117] Prior Art inflatable craft cannot approach these alternative embodiments of the stewcraft tm inflatable in the areas of design, utility and operational applications.

[0118] Ramifications/Conclusions:

[0119] The patent application is for a new use and new design inflatable watercraft with means for shelter and walking support around the (horizontal) circumference.

[0120] The craft is also designed with a nose assembly which can impact, bump and push other floating objects without damage to the main structure of the item pushed/bumped or damage to the new design inflatable.

[0121] Th upper portion of the craft consists of a deck and cabin assembly: the lower portion of the craft consists of an inflatable pontoon.

[0122] The result is a large, utilitarian, seaworthy floating surface with 60% to 75% more usable space and a striking new and more attractive appearance for inflatable watercraft. The new design inflatable is also substantially more seaworthy than the prior art inflatable pontoon or raft.

[0123] The new combination of hard top with an inflatable body creates the best of two boating worlds in that the low profile, agility and rugged character of an inflatable are combined with the top side features and advantages of conventional boats.

[0124] These combined features create a new synergism in boating excitement and utility: the new principle* of operation and design allows inflatable to cross the line by making a quantum leap in previously unimagined uses and applications.

[0125] This is a hybird craft, which can be operated and used in significant and substantial ways that were not possible and not obvious with the use of either type of prior art by itself.

[0126] For example, it is unobvious to a person skilled in the art that the hard top assembly can be attached with straps, yet the hard top assembly will not fall off even with rugged and extended use. It is unobvious that the top portion can be permanently built on to the inflatable pontoon, yet the preferred approach is to make it somewhat or completely removable for necessary inspections, maintenance and repairs. As well as for transport or storage.

[0127] Further, a hardbody craft could not bump or impact another (hard) craft without damage and a conventional inflatable could not accommodate personnel on the deck area because it has no such area: yet the hybird craft can do both. I.e. bump, impact or push a hardbody craft without damage to either, as well as accommodate personnel on the deck area at the same time.

[0128] In part, the novel design and unobvious utility of the nose portion of the new design inflatable allows for this increased bumping and impact absorption capacity.

[0129] A generic inflatable, for example, is not designed nor intended to bump, impact or push other floating objects.

[0130] Indeed, the flexible, soft character of the generic inflatable operates to limit the capacity or degree to which the generic inflatable pontoon can accomplish these things.

[0131] In contrast, our new design inflatable has a more rigid character which can accomplish these bumping or pushing tasks by design and do so more effectively.

[0132] Also, those familiar with the prior art have not devised a way to accommodate a full electrical panel in a n inflatable craft, and this full electrical panel can pave the way for the for introduction of many of the accessories which conventional hard body craft carry as a routine matter.

[0133] Prior to the development of this new design inflatable boat, there has been no suggestion in the field to the effect that an inflatable boat could be built to accommodate practically the full component of equipment that a conventional hard body boat comes equipped with.

[0134] It is, perhaps, quite unobvious that the key to accommodating a full electrical panel lies in the holes cut through the temples.

[0135] These holes make it possible to securely install and safely pass electrical wires and cable throughout the inflatable, allowing for the introduction of lights, heaters, radar, Etc.

[0136] The holes cut in the templates are not for water to pass through, as some skilled in the art have presumed: they have a very novel, unobvious and strategic purpose in the overall design of the new inflatable watercraft.

[0137] Without this feature in the design of the templates it would be ackward or impossible to accommodate as many of the features of conventional hard body craft on the inflatable watercraft.

[0138] It is possible to venture out into the ocean with these new design inflatables, provided an experienced seaman is operating the craft; however, the craft is recommended primarily for use in the waterfront, along the coast or at inland rivers and lakes.

[0139] The novice can operate this craft with the same degree of skill that it takes to operate a conventional inflatable; and the experienced seaman can test the limits of his skills in the open ocean provided he first equips this craft with the accessories necessary to venture out into the sea. Indeed, the craft can be designed to be exceptionally seaworthy however, as with any vehicle, after a critical factor when one goes beyond the threshold of conventional use.

[0140] The professional race car driver does not perform in a conventionally equipped vehicle yet he must have exceptional skills in operating the craft. Similarly, this new design inflatable can open the door to a new water sport for skilled professionals.

[0141] Some expanded 1) recreational, 2) commercial, 3) military, 4) scientific, and 5) emergency/rescue/search applications include:

[0142] 1) RECREATIONAL: Long distance, over night, ocean or river rough water uses not possible with the previous art.

[0143] 2) COMMERCIAL: Demand for this type of craft includes customers who cannot afford a conventional boat as well as those who have a conventional boat or yacht and can use this as a dingy and evacuation craft that can carry more people and survival equipment than the previous art.

[0144] 3) MILITARY: The low profile creates a stealth aspect which in some applications is below radar range and can approach a target or invasion location with more personnel, equipment, safety, stability as well as with capacity to carry operational offensive/defensive weapons than is possible with the prior art of the same size.

[0145] 4) SCIENTIFIC: The use of an electric troll motor which can be permanently attached to the deck as well as the capacity of this boat to carry heavy yet sensitive scientific equipment to remote locations without disturbing the natural environment provides for multiple scientific uses and applications not possible with the prior art.

[0146] 5) EMERGENCY/RESCUE/SEARCH: This new design inflatable allows for a more prolonged search though greater protection from the elements, through the increased capacity to carry emergency equipment, and provides greater comfort to the person rescued. Beach and lifeguard surveillance and rescue would acquire new dimensions and new rescue protocols would be possible through the use of this craft off-shore e.g. the physical stamina of the lifeguard can be reserved for the point of contact with the rescued person; significantly increased in emergency cases where seconds can mean the difference between life and death for a distressed swimmer. Life saving treatment can begin immediately on the craft, whereas conventional lifeguard rescue methods require the physical movement of the victim to safety, only after which life saving procedures can begin.

[0147] The craft, with its shallow draft can be operated in very shallow water as well as in relatively rough ocean waters. Its relatively lightweight makes it possible to lower it into remote inland waterways where it would be impractical to attempt to place and operate a conventional hard body craft.

[0148] This new design inflatable can accommodate a chemical toilet, a microwave or portable stove, and it can more conveniently, safely and comfortably be used for overnight travel than a prior art inflatable.

[0149] Indeed, the larger inflatables designed in this manner can be built to also accommodate limited sleeping quarters and a shower.

[0150] These new design inflatable watercraft are intended to have a low initial cost compared to conventional hard body boats with corresponding accessories; this watercraft is significantly and suprisingly more seaworthy then the prior art inflatable pontoons.

[0151] Yet, it is not the purpose to create a luxury type inflatable craft; rather, this is more of a rugged craft very mush as the “Hummer” vehicle is more comfortable and elegant than a “Jeep”, though it was not intended to be a Cadillac or Lincoln.

[0152] The prior art also maintains a decided emphasis on the soft body character of the craft, with the presumption that the inflatable can be easily and quickly deflated and reinflated as the need arises.

[0153] However, in practice it is often the case that once an inflatable boat is inflated, it remains inflated pretty much for the life of the boat.

[0154] The new design inflatable is designed to be disassembled along with the deflating properties of the air filled pontoon; then, of course, the unit can be transported using less than when fully assembled and inflated.

[0155] Yet, we anticipate that for the most part, the hard top inflatable will remain fully assembled very much as the prior art inflatables are kept fully inflated once they are put to use.

[0156] There are great advantages in having a hard top surface area on a craft that has conventionally been thought of as a soft; air filled pontoon or raft.

[0157] For instance, it would be difficult or impossible to install a fixed troll motor or to attach permanent metal cleats on top of a flexible air filled surface.

[0158] Needless to say, the air would escape from the pontoon if this were attempted on a prior art inflatable.

[0159] Similarly, in the case of installing a secure fixed metal rail around the circumference of the prior art inflatable.

[0160] Indeed, this can be accomplished on a prior art soft body inflatable, however it would be unstable, unreliable and its utility would be limited without a hard, durable, stable surface upon which to securely anchor the fixed metal rail.

[0161] The deck is designed, in part, to reach beyond the transom at the rear of the boat: this has the benefit of allowing significantly greater access to the outboard engine(s) while the boat is in the water. Even conventional hard body craft lack this feature, which can be a critical asset in an emergency situation.

[0162] In summary, the hybrid craft produces unexpected results by combining the features of conventional hard body craft with those of inflatables and the combination has proven to work extremely well.

[0163] To date, the possibility of this combination has gone unrecognized, the advantages unappreciated and until now, has not been implemented.

[0164] This invention has added significant to the sum of human knowledge in the capability and design of inflatable boats as we know them; the invention contributes to making the world's work easier, cheaper and safer by allowing the conversion of a low-lying rubber bladder into a sophisticated scientific tool or multi-purpose recreational vehicle. We have outlined only a few of the possible recreational, commercial, military, scientific and emergency applications which this new design inflatable craft makes possible. A return to the prior art would be retrogression since inflatable, as we know them are not capable of these more sophisticated applications.

[0165] The material contribution this new design inflatable makes to a crowded field is significant and unique: for example, in our application of this new design inflatable, we have created more of an “off-road-vehicle” for the oceans, rivers and lakes. It is not intended as a luxury vehicle of the watercraft, rather its applications excel as a “utility vehicle of the water”. It has been a long time that the previous art has needed these improvements yet has gone without them.

[0166] The fact that those skilled in the art have not implemented the invention despite its great advantages indicates that this invention is not obvious. Of course, if the invention were infact obvious, because of its advantages, those skilled in the art may well have implemented it by now.

[0167] Having developed and tested this craft, it is apparent that it fills a large void, addresses an unsolved need and provides a syngerism for further innovation and refinement of this hybrid watercraft.

[0168] It was the initial intent in building this craft to design a relatively low cost vehicle, which could safely accommodate the children of growing families.

[0169] As we know, growing families often have many expenses, and including the cost of a boat in the family budget is out of the question for many families.

[0170] The new design inflatable opens the door to the environment of the offshore environment to many people who, up to now, have had to remain on shore because they could not afford the “luxury” of going for a boat ride.

[0171] The “exclusive” nature of the boating world is now less so foe children as well as for the Adult fishing enthusiasts who have been restricted to the shore for lack of an affordable watercraft. 

Our claims include, but are not restricted to the following domain:
 1. “A UTILITY DESIGN INFLATABLE WATERCRAFT WITH MEANS FOR SHELTER AND CIRCUMFERENCE WALKING SUPPORT.”
 2. “A HYBIRD WATERCRAFT CONSISTING OF A HARDBODY DECK AND CABIN BUILT OVER AN INFLATABLE PONTOON.”
 3. “A HARDTOP ASSEMBLY/APPARATUS WHEREBY AN INFLATABLE PONTOON IS TRANSFORMED INTO A LARGE, SEAWORTHY, UTILITARIAN FLOATING WATERCRAFT.”
